SHUTTLE-BOX-OPERATING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 693,681, dated February 18, 1902.

Application filed November 18, 1901. Serial No. 82.618. (No model.)

To all whom, it may concern.-

Be it known that I, HENRY BARDsLEY, acitizen of the United States, residing at Providome, in the county of Providence, State of Rhode Island, have invented a certain new and useful Improvement in Shuttle-BoX-Opcrating Mechanisms for Looms, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention has relation to shuttle-boxoperating mechanism of that class in which an intermittingly-operated master-gear partially rotated step by step is employed for the purpose of actuating, under the control of i5 pattern devices, the train or trains of operating and transmitting connections through which the box-lever is moved to shift the shuttle-boxes and in which a train such as just has been referred to comprises a partially-toothed or mutilated pinion which at times is engaged and given a semirevolution by the said master-gear, a crank or eccentric rotating in unison with said pinion, and operative connections from said crank or eccentrio to the box-lever.

The object of the invention is to provide means for causing further actuation of the partially-toothed or mutilated pinion or pinions aforesaid by the master-gear to be pre- .30 vented when the weft-detector devices act to indicate the occurrence of the predetermined condition of the weft or filling, thereby preventing any further change or shift of the position of the shuttle-boxes during the continned working of the loom mechanism.

The invention consists in the novel devices which I will now proceed to explain with reference to the accompanying drawings, in which latter I have shown the best embodiment of the invention which I have thus far contrived.

In the accompanying drawings, Figure 1 shows in side elevation portion of one side frame of a loom having the said embodiment of the invention applied thereto. Fig. 2 is a plan View, partly in section, showing the compound box-lever. Fig. 3 is a detail view illustrating a convenient and well-known arrangement of weft-detector devices and the manner of operating therefrom the disengaging 5o device, to which reference is made hereinafter. Fig. 4 is a detail view in elevation showing the mastergear, one of the partiallytoothed or mutilated pinions, and the disengaging device. Fig. 5 shows the parts of Fig. 4 in side elevation.

Having reference to the drawings, 1 designates portion of one of the side frames of a loom.

5 is the master gear. It is in practice moved intermittingly the distance of a partial revolution, as usual. Any suitable or known operating means therefor may be provided-as, for example, means similar to that of my United States Letters Patent No. 681,648, granted August 27, 1901. 54 is the sleeve of the master-gear, and 4 is the segmental gear on said sleeve, as in the said patent.

51 51, &c., are the toothed segments with which the master-gear 5 is provided for the actuation of the partially-toothed or mutilated pinions.

One of the partially-toothed or mutilated pinions is shown at 6, Figs. 1, 4, and 5, the places of two more of such pinions being indicated by dotted circles in Figs. 1 and 4. Each of the said pinions has connected therewith a crank, as 61, or other motion-transmitting device, the said crank in the present instance being connected by means of a link or connecting-rod, as 62, with the box-lever. The number of pinions employed and the character and arrangement of the box-lever will vary according to the number of cells that is contained in the series of shuttle-boxes. The said cells vary in number in different cases in practice as required. The illustrated mechanism has been designed for operating a series of shuttle-boxes containing six cells. Accordingly there are three pinions, and the box-lever 7 is a compound lever. What for the purposes of this case may be termed the main lever 71 of the box-lever is connected pivotally with the forward extremity of the secondary lever 72. The main lever 71 has pivotally connected with its forward extremity the link 8, extending upward and con nected pivotally with the box-rod 8'1 and has connected with its rear extremity one of the connecting-rods 62. The secondary lever 72 has connected therewith two of the said connecting-rods, one at the rear extremity thereof and one at an intermediate point. The action of the cranks in operating the compound box-lever and shifting the shuttleboxes is well understood by those who are skilled in the art. At 9 is shown a radius-arm, which has one extremity pivotally connected with the rear extremity of the main lever 71, while the other extremity of said radius-arm is pivoted, as at 91, to the side frame 1 of the loom, this radius-arm serving to steady the compound box-lever in its movements.

Each mutilated pinion 6 in the illustrated embodiment of the invention is furnished withadia metrical lever 10 on the order of that which is shown and described in my prior United States Letters Patent, No. 626,960, granted June 13, 1899, the respectivediametrical levers being controlled, as in the said patent, by a pattern-surface and intervening operative connections, the said connections comprising in part the levers or fingers 11 111 112 and rock-shafts 12 121.

At 52 52, &c.,are the starting-teeth with which the master-gear 5 is provided. The said starting-teeth are designed to engage in the rotation of the master-gear with the inwardly-directed extremities of the diametrical levers when the said levers are swung by the pattern connections into position to place the said inwardly-directed extremities thereof within the range of movement of the starting-teeth 52 52. This engagement operates to partially rotate the predetermined pinion or pinions far enough to bring teeth of the latter around for engagement with the segments 51 51 of the master-gear, whereby the said segments of the master-gear are enabled to occasion a semirevolution of the said predetermined pinion or pinions.

At 53 53, &c., are shown the plain concentric surfaces or rests with which the mastergear is provided intermediate the segments 51 51, &e., for coaction with the toothless portions 61 61 of the pinions 6 in holding the pinions from rotating between the predetermined times of movement therefor.

No novelty is claimed for the foregoing features, all of which are or may be essentially as heretofore.

As will be apparent the extremities of the diametrical levers constitute movable starting-teeth for the mutilated pinions, the said extremities being brought within the range of action of the starting-teeth of the mastergear by the pattern mechanism when it is desired that a pinion shall be given a semirevolution.

For the purpose of preventing further actuation of the mutilated pinion or pinions by the master-gear after the weft-detector devices have acted to indicate the occurrence of the predetermined condition of the weft or filling I provide means in operative connection with the weft-detector devices and by which on such occurrence working relations between the mutilated pinion or pinions and the'master-gear are disestablished through the action of said weft=detector devices. The desired result may be effectuated in Various ways within the spirit of my invention. The said invention is not restricted to the particular embodiment that is illustrated in the drawings. In constructions having startingteeth which are shifted by the pattern mechanism into engaging position for the purpose of bringing about a change of the shuttleboxes the said result is attained by causing such starting-teeth to occupy positions in which engagement cannot occur. In the present embodiment of the invention I provide means for causing the diametrical levers to occupy positions in which their inwardlydirected extremities are out of the range of movement of the starting-teeth with which the master-gear is furnished. Preferably, although not necessarily in all embodiments of the invention, the said means is caused to engage with the said inwardly-directed extremities. In the drawings a rotary disengager Ct is shown, it being mounted concentrically with relation to the mastergear. The said disengager is provided with a series of arms a a a ct to act against the inwardlydireeted extremities of the diametricallevers and with a sleeve a Fig. 5, fitted within sleeve 54 of the master-gear. The arms a a, 850., project radially outward from the center of the master-gear, the extremities thereof entering into the intervals between the toothed segments 51 51,&c. ,of the master-gear.

The said toothed segments have at the opposite ends thereof inwardly-extending enlargements 54 54:. The extremities of the arms a a, &c., fit between pairs of these enlargements, as shown in Fig. 1, and by the engagement of the said enlargements with the disengager the latter in the present embodiment of the in vention is caused to rotate in unison with the master-gear. The normal position of the disengager (shown by dotted lines in Fig. 5) leaves the diametrical levers free to be moved by the action of the pattern mechanism in a direction to carry the inwardly-directed extremities of said levers laterally within the intervals between the pairs of starting-teeth 52 52 into position to be engaged by said starting-teeth in the rotation of the master-gear to start the pinions 6. (See the dotted-line position of lever 10 in Fig. 5.) Movement of the disengager laterally outward from its position in Fig. 5 will cause it to hold the levers 10 in a position to clear the startingteeth 52 52, &c. The said starting-teeth are constituted by the opposite ends of flanges b b, &e., projecting laterally from the segments 51 51, 850., of the master-gear. The edges of these flanges while passing the diametrical levers act to hold the inwardly-directed extremities of the latter clear of the ends of the teeth of the segments 51 51.

The 'disengager may be operatively combined with any suitable form or arrangement of weft-detector devices. In Fig. 3 I have shown simple weft-fork mechanism, the same comprising, essentially, the gooseneck a, only part of which is shown, the weft-fork 0, its slide d, mounted on top of breast-beam cl, and the rod e, mounted beneath the breastbeam in bearings, in which it is free to rock, and provided with the arm e, arranged to be acted against by the slide (Z. Rod 6 is provided also with the arm c which is connected by a wire or rodfwith arm g on a rock-shaft g, extending from front to rear in the loom, the said rock-shat t being furnished at its rear end with a shipper-fork h, engaging with the grooved hub 'i on the sleeve a of the disengager. YVhen the weft or filling fails or breaks and the tail of weft-fork c is engaged by gooseneck 0, so that the slide (Z is pushed forwardly on the breast-beam and rod e is turned, rocking the rock-shaft g, the shipperfork h on said rock-shaft acts to move the disengager out of its normal inoperative position, (shown in dotted linesin Fig. 5,) so as to'hold the diametrical levers out of engagement with the starting-teeth 52 52, &c., of the master-gear.

What I claim is- 1. In combination, the master-gear, the mu tilated pinion and its motion-transmitting connections, weft-detector devices and means under operative control of said weft-detector devices whereby operative relations between the master-gear and pinion are disestablished on the occurrence of the predetermined condition of the weft, substantially as described.

2. In combination, the master-gear, the mutilated pinion and its motion=transmitting connections,weft-detector devices, and means under operative control of said weft-detector devices whereby engagement of said mutilated pinion by said master-gear to actuate the former is prevented on the occurrence of the predetermined condition of the weftor filling, substantially as described.

3. In a loom, an organized mechanism comprising, essentially, in combination, a mastor-gear and a mutilated pinion having starting-teeth which are adapted to be shifted into engaging position to occasion the actuation of the said pinion, pattern connections to control such shift, weft-detector devices, and means under operative control of said weftdetector devices whereby said starting-teeth are caused to occupy an inoperative position to thereby prevent the actuation of the pinion, substantially as described.

4. In combination, the master-gear, the mutilated pinion, and its diametrical lever, pattern connections in control of saidlever, Weftdetector devices, andmeans under operative control of said weft-detector devices whereby engagement of said lever by said master-gear is prevented on the occurrence of the predetermined condition of the weft or filling, substantially as described.

5. In combination, the master-gear, the mutilated pinion and its diametrical lever, pattern connections in control of said lever, the disengager coactin g with said lever, and weft detector devices, in operative control of said disengager whereby engagement of said lever by said master-gear is prevented on the occurrence of the predetermined condition of the weft or filling, substantially asdescribed.

6. In combination, the master-gear, the mu tilated pinion and its diametrical lever, pattern connections in control of said lever, the disengager at the side of said master-gear, and weft-detector devices having operative connections with said disengager whereby to move the same laterally, substantially as described.

7 In combination, the master-gear, the mu tilated pinion and its diametrical lever, pat tern connections in control of said lever, the disengager at the side of said master-gear and rotating in unison therewith, and weft-detector devices having operative connections with said disengager whereby to move the same laterally, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.-
